METHOD FOR MANUFACTURING ANILINE |
| 摘要 |
Crude aniline is produced by hydrogenating nitrobenzene in the presence of a catalyst. This crude aniline is then purified by means of a single-step or multi-step distillation process in which aqueous alkali metal hydroxide solution is added to the crude aniline prior to distillation and/or during distillation of the crude aniline. |
